f) If the dose rate with a particular equipment exceeds this criterion a
stated in above one of the following courses of action should be taken:
i) Use a container and accessories which provide more shielding for the
operator.
ii) Reduce the strength of the sealed source.
iii) Use a projection type container.
iv) As last resort, reduce the work load of the individual operator so that
he shall not receive an excessive dose.
g) For a given job the source strength sold be selected to give reasonable
exposure times compatible with acceptable doses to the operator. For
example if a strong source is used for radiography of small pipe the
exposure times may be too short to enable the operator to work in a
safe manner.
